晚期糖尿病(diabetes mellitus，DM)患者常出现的糖尿病性视网膜病变能够被发现，而糖尿病性角膜病变(diabetic keratopathy，DK)却时常被人们忽略。近年来的许多研究表明，DK对角膜的结构、代谢、生理功能等多个方面均有重要影响。目前临床上尚无根治DK的有效疗法，现主流疗法多集中于对症治疗以维持光滑湿润的眼表，最大限度地减少视觉损失以及提高舒适度，如局部滴用人工泪液、使用角膜绷带镜及局部使用抗炎药物等，但这些现有的治疗方法对于角膜组织损伤的修复能力有限。近年来出现神经生长因子、胰岛素疗法等新兴的治疗方法，有望未来应用于临床。

The diabetic retinopathy which often occurs in patients with advanced diabetes mellitus (DM) can usually be realized, but diabetic keratopathy (DK) could sometimes be ignored. In recent years, many studies have found out that DK can cause significant abnormal changes in many ways, including structure, metabolism and physiological functions of the cornea. At present, there is no effective therapy to cure DK. The current mainstream therapy mostly focuses on symptomatic treatment to maintain a smooth and moist ocular surface, minimize visual loss and improve comfort, such as local drip of artificial tears, use of corneal bandage lens and local use of anti-inflammatory drugs. However, these existing treatment methods have limited repair ability for corneal tissue damage. In recent years, a number of new treatment methods have emerged, which are expected to be clinically used in the future, such as nerve growth factors and insulin therapy.

Objective: To conduct a pre-course survey on the graduate students who participated in the Molecular Medicine Laboratory Skills Training Course in the Zhongshan Ophthalmic Center of Sun Yat-sen University to provide a reference for the preparation of the course. Methods: We asked the doctoral and master’s students who participated in the training courses of molecular medical experimental skills in 2020 and 2021 to take a pre-course questionnaire survey and analyzed the results by the students’ pre-course command of theoretical knowledge and pre-training operational experience in 15 lessons of special topics or techniques. Results: A total of 155 students completed the pre-course questionnaire survey. Our results showed that there were 14 lessons in which more than 25% of the students were not familiar with the theoretical knowledge, whereas there were 6 lessons in which less than 10% of the students had high operational proficiency. The students majoring in the molecular medicine had better prior knowledge of the techniques: there were only 9 lessons in which more than 25% of the students were not familiar with the theoretical knowledge, whereas there were 12 lessons in which less than 10% of the students had high operational proficiency. The four lessons with worst prior knowledge were cell proliferation, flow cytometry, image acquisition, and omics analyses. We grouped the 15 lessons into 7 categories: the ophthalmic experimental data collection, the omics technology, the data analyses, the cell technology, the protein technology, the tissue analyses, and the molecular technology, presenting by the level of the students’ pre-training proficiency from low to high. Conclusion: The first-year graduate students were very weak in basic knowledge and had little experience in techniques before joining the molecular medicine training courses. It is urgent to improve the laboratory skills training system and strengthen the construction of the curriculum system.

Objective: To evaluate the current status and correlations between attitudes and competency for interpersonal communication in ophthalmology standardized training trainee. Methods: A questionnaire survey was conducted on the communication attitudes and interpersonal communication ability of standardized training trainees from three grades in Zhongshan Ophthalmic Center, affiliated to Sun Yat-sen University, and the correlation between communication attitude and communication ability was further analyzed. Results: A total of 196 trainees were included. The scores of positive attitude, negative attitude, and interpersonal communication skills were 51.38±6.52, 36.80±5.70, and 2.41±0.40, respectively. In addition, the dimension of coaching and counseling scores were 2.50±0.64, the dimension of providing effective and negative feedback scores were 2.61±0.50, and the dimension of supportive communication scores were 2.29±0.44. The positive attitudes of communication skills were significantly related to the interpersonal communication skills and three-dimensionality (P<0.01). The interpersonal communication skills were significantly associated with sex, grades, interest in ophthalmology, social support from the family and friends (P<0.05). Conclusion: Ophthalmology trainees have excellent positive attitudes toward communication skills, but the overall communication skills are weak and influenced by a variety of factors. More attention should be paid to the development of interpersonal communication skills of the trainees, and specialized training in doctor-patient communication is warranted.

目的：评估屈光不正患者有晶体眼后房型人工晶体(implantable collamer lens，ICL)植入术后视疲劳症状及调节集合功能、眼表、像差的变化，并探讨其对视疲劳症状的影响。方法：前瞻性病例观察分析。连续收集在沧州市中心医院行ICL手术并完成3个月随访的患者，测定术前、术后1周、1个月、3个月时的视疲劳评分、调节幅度(amplitude of accommodation，AA)、正相对调节和负相对调节(positive/negative relative accommodation，PRA/NRA)、调节灵敏度(accommodative facility，AF)、调节性集合(accommodative convergence，AC)与调节(accommodation，A)比率(AC/A)，Schirmer实验、非侵入性泪膜破裂时间(noninvasive breakup time，NBUT)及高阶像差(higher order aberration，HOA)，进行统计学分析。结果：ICL术后第1周视疲劳症状较术前明显加重，随时间推移逐渐减轻，术后1个月仍高于术前，术后3个月时恢复。AA术后1周时较术前降低，术后1个月、3个月时明显高于术前；AF术后1周时较术前下降，术后1个月比术前水平稍好，3个月时明显高于术前；PRA、NRA无明显变化；AC/A术后1周时较术前下降，术后1个月回复到术前水平，术后3个月较术前提高。术后1周、1个月及3个月的NBUT值均较术前明显下降，术后1周时最低；Schiermer值术后1周时轻度下降，术后1个月、3个月时基本恢复。术后的总HOA均较术前有所增加，但各个时间点之间无明显变化。相关性分析显示ICL术后AF越差、NBUT越低，视疲劳症状越重。结论：ICL术后视疲劳症状一过性加重，AF和NBUT是影响视疲劳变化的重要因素。

Objective: To evaluate the changes of visual fatigue symptoms, accommodative functions, ocular surface conditions, and high-order aberrations (HOA) after implantation of implantable collamer lens (ICL), and to explore their effects on asthenopia. Methods: It was a prospective observational case series. Patients with ametropia who underwent ICL surgeries and completed 3-month follow-up in our hospital were enrolled.Asthenopia scores, amplitude of accommodation (AA), positive/negative relative accommodation (PRA/NRA),accommodative facility (AF), the ratio of accommodative convergence and accommodation (AC/A), Schirmer test, non-invasive breakup time (NBUT), and HOA were examined before surgeries and at 1 week, 1 month and 3 months after surgeries, then statistically analyzed. Results: Symptoms of asthenopia were significantly worse at 1 week after ICL surgeries than those before surgeries, but increased gradually as time went by, eventually recovered at 3 months postoperatively. Among regulatory indicators, AA decreased 1 week postoperatively, but was significantly higher at 1 and 3 months after surgeries; AF was lower 1 week after surgery than baseline, slightly better at 1 month postoperatively, and significantly higher at 3 months postoperatively; PRA and NRA had no significant change; AC/A decreased 1 week after surgeries, returned to the baseline at 1 month postoperatively, and increased 3 months postoperatively. Tears and meibomian gland function index: NBUT values at 1 week, 1 month and 3 months after surgeries were significantly decreased compared with those before surgeries, and NBUT at 1 week postoperatively was the lowest; Schiermer values had a slight decrease at 1 week after surgeries, and basically recovered at 1 and 3 months after surgeries. HOA after surgeries were increased compared with those before surgeries, but there was no significant change between each time point. Correlation analysis showed that the lower AF and NBUT after ICL surgeries, the more severe the asthenopia symptoms. Conclusion: The symptoms of asthenopia aggravated transiently after ICL implantation surgeries, but improved gradually with time. AF and NBUT were important factors affecting the changes of asthenopia.

球后阻滞是眼科手术中常见的麻醉方式之一，若操作不当，可造成严重并发症，包括局部麻醉药物的毒性反应等。现报告1例26岁诊断为“视网膜脱离”拟行眼底手术的女性患者，在球后阻滞10min后，患者出现心率增快、血压升高后下降、吞咽困难、声音嘶哑、呼吸困难及SpO2下降，伴随对侧眼球运动障碍，全身肌力下降等临床表现。及时给予生命支持等对症处理后，患者上述临床表现好转，并随后在全身麻醉下完成手术。

Retrobulbar block is one of the common anesthesia methods in ophthalmic surgery, however, misconducting the procedure would result in severe complications including central toxicity from local anesthetics. This study presented a 26-year-old female patient diagnosed retinal detachment for retinal surgery under retrobulbar block, 10 min after anesthesia, the patient initially exhibited increased heart rate and blood pressure, inability to swallow secretions (sputum), hoarseness, and dyspnea, then SpO2 decreased, the patient displayed contralateral eye movement disorder, reduced systemic muscle strength and other clinical manifestations. The condition was improved with the treatments for life support, and the surgery completed uneventfully under general anesthesia with tracheal intubation.

近年来，眼科手术后的疼痛受到关注，部分患者术后表现出疼痛区域扩大，神经性畏光。术后这种 对伤害性刺激性信号反常性增加的现象称之为痛觉过敏。痛觉过敏的发展会导致患者延迟术后恢 复等问题。此外，痛觉过敏还会引起患者不适，诱使患者使用更多的止痛药而产生相关的不良反 应。而TRPV1/TRPA1是一种伤害性感受器，能够被伤害性刺激特异性激活而诱发痛觉过敏。尽管 如此，目前关于眼科术后的痛觉过敏发病机制未完全阐明，TRPV1如何增敏导致痛觉过敏的分子生 物学过程尚未明确。

The postoperative pain of ophthalmic surgery has been widely concerned in recent years. Some patients show enlarged painful areas and neurophotophobia postoperatively. This abnormal increase in noxious irritant signals after surgery is called hyperalgesia. The development of hyperalgesia can result in delayed postoperative recovery for patients. In addition, hyperalgesia can also cause discomfort for patients, and induce patients to use more analgesics, which can have related side effects. TRPV1/TRPA1 is a nociceptor, which can be specifically activated by nociceptive stimuli to induce hyperalgesia. Nevertheless, the pathogenesis of hyperalgesia after ophthalmology surgery has not been fully elucidated, and the molecular signal pathway of how TRPV1 sensitizes and causes hyperalgesia is not yet clear.
